What type of tissue surrounds the kidneys?
The kidneys are surrounded by three layers of tissue: The renal fascia is a thin, outer layer of fibrous connective tissue that surrounds each kidney (and the attached adrenal gland) and fastens it to surrounding structures. The adipose capsule is a middle layer of adipose (fat) tissue that cushions the kidneys.
What are the filtering parts of the kidney?
The kidney consists of over a million individual filtering units called nephrons. Each nephron consists of a filtering body, the renal corpuscle, and a urine‐collecting and concentrating tube, the renal tubule. The renal corpuscle is an assemblage of two structures, the glomerular capillaries and the glomerular capsule, shown in Figure 1.
What passes through the hilus of the kidney?
The ureter, nerves, and blood and lymphatic vessels enter the kidney on the concave surface through the renal hilus. The renal sinus houses the renal pelvis, a funnel‐shaped structure that merges with the ureter. Because the major function of the kidneys is to filter the blood, a rich blood supply is delivered by the large renal arteries.
What are the different parts of the kidney?
Your kidneys, which are the main part of the urinary system, are made up of millions of nephrons that act as individual filtering units and are complex structures themselves. The ureters, urethra, and urinary bladder complete this intricate system.
Which tissue type would hold the kidneys in place?
Each kidney is held in place by connective tissue, called renal fascia, and is surrounded by a thick layer of adipose tissue, called perirenal fat, which helps to protect it.
What type of tissue keeps organs in place?
Loose connective tissueLoose connective tissue works to hold organs in place and is made up of extracellular matrix and collagenous, elastic and reticular fibers. Dense connective tissue is what makes up tendons and ligaments and consist of a higher density of collagen fibers.
Which tissue would mostly be useful for holding internal organs in proper place?
Loose connective tissue, show below, is the most common type of connective tissue. It's found throughout your body, and it supports organs and blood vessels and links epithelial tissues to the muscles underneath.
What tissue is in the body providing support binds and storage places?
Connective tissue is the tough, often fibrous tissue that binds the body's structures together and provides support and elasticity. It is present in almost every organ, forming a large part of skin, tendons, joints, ligaments, blood vessels, and muscles.
What is connective tissue function?
Listen to pronunciation. (kuh-NEK-tiv TIH-shoo) Tissue that supports, protects, and gives structure to other tissues and organs in the body. Connective tissue also stores fat, helps move nutrients and other substances between tissues and organs, and helps repair damaged tissue.
What is the location of connective tissue?
Fibrous Connective Tissue Irregularly-arranged fibrous connective tissues are found in areas of the body where stress occurs from all directions, such as the dermis of the skin. Regular fibrous connective tissue is found in tendons (which connect muscles to bones) and ligaments (which connect bones to bones).
What is loose connective tissue function?
Loose connective tissue is found between many organs where it acts both to absorb shock and bind tissues together. It allows water, salts, and various nutrients to diffuse through to adjacent or imbedded cells and tissues. Adipose tissue consists mostly of fat storage cells, with little extracellular matrix ((Figure)).
Which tissues will be suitable for supporting and protecting vital organs Why?
Supportive Connective Tissues. Two major forms of supportive connective tissue, cartilage and bone, allow the body to maintain its posture and protect internal organs.
What is supportive connective tissue?
Supportive connective tissue—bone and cartilage—provide structure and strength to the body and protect soft tissues. A few distinct cell types and densely packed fibers in a matrix characterize these tissues. In bone, the matrix is rigid and described as calcified because of the deposited calcium salts.
What type of tissue binds organs together?
Connective tissueConnective tissue, as its name implies, binds the cells and organs of the body together and functions in the protection, support, and integration of all parts of the body.
What type of tissue binds body tissue together?
Connective tissue supports other tissues and binds them together (bone, blood, and lymph tissues).
What type of tissue binds things together?
Connective tissues bind structures together, form a framework and support for organs and the body as a whole, store fat, transport substances, protect against disease, and help repair tissue damage. They occur throughout the body.
What are the 4 tissue types and their functions?
Epithelial tissues act as coverings controlling the movement of materials across the surface. Connective tissue integrates the various parts of the body and provides support and protection to organs. Muscle tissue allows the body to move. Nervous tissues propagate information.
Where are your organs placed?
The abdominal organs may be classified as solid organs, or hollow organs. The solid organs are the liver, pancreas, spleen, kidneys, and adrenal glands. The hollow organs of the abdomen are the stomach, intestines, gallbladder, bladder, and rectum....Organ (biology)OrganFMA67498Anatomical terminology5 more rows
What is epithelial tissue and its function?
Epithelial tissues are widespread throughout the body. They form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands. They perform a variety of functions that include protection, secretion, absorption, excretion, filtration, diffusion, and sensory reception.
What is squamous tissue?
Squamous, or flattened, epithelial cells, very thin and irregular in outline, occur as the covering epithelium of the alveoli of the lung and of the glomeruli and capsule of the kidney. Ciliated epithelium lines the trachea, bronchi of the lungs, parts of the nasal cavities,…
What is the outer layer of the kidney?
The kidneys are surrounded by three layers of tissue: The renal fascia is a thin, outer layer of fibrous connective tissue that surrounds each kidney (and the attached adrenal gland) and fastens it to surrounding structures. The adipose capsule is a middle layer of adipose (fat) tissue that cushions the kidneys.
Where are the capillaries located in the renal cortex?
These capillaries weave around the portions of the renal tubule that lie in the renal cortex. In portions of the nephron loop that descend deep into the renal medulla, the capillaries form loops, called vasa recta, that cross between the ascending and descending limbs.
What is the PCT in the renal cortex?
The first section, the proximal convoluted tubule (PCT), exits the glomerular capsule as a winding tube in the renal cortex. The wall of the PCT consists of cuboidal cells containing numerous mitochondria and bearing a brush border of dense microvilli that face the lumen (interior cavity).
What are the two structures of the nephron?
The renal corpuscle is an assemblage of two structures, the glomerular capillaries and the glomerular capsule, shown in Figure 1. The glomerulus is a dense ball of capillaries (glomerular capillaries) ...
How is Na+ transported out of the tubule cells?
Thus, Na + in the tubule cells is transported out of the cells and into the interstitial fluid by active transport. The Na + in the interstitial fluid then enters the capillaries by passive diffusion. (The K + that is transported into the cell leaks back passively into the interstitial fluid.)
How do substances move out of the tubule?
Movement of substances out of the tubule, then, must occur through the cells, either by active transport (requiring ATP) or by passive transport processes. Once outside of the tubule and in the interstitial fluids, substances move into the peritubular capillaries or vasa recta by passive processes.
What are the main parts of the urinary system?
Your kidneys, which are the main part of the urinary system, are made up of millions of nephrons that act as individual filtering units and are complex structures themselves. The ureters, urethra, and urinary bladder complete this intricate system. The urinary system helps maintain homeostasis by regulating water balance ...
