What are the gross anatomy of the kidney?
The kidneys lie on either side of the spine in the retroperitoneal space between the parietal peritoneum and the posterior abdominal wall, well protected by muscle, fat, and ribs. They are roughly the size of your fist, and the male kidney is typically a bit larger than the female kidney.
How will you describe the structure of the kidney and its coverings?
The kidneys are a pair of bean-shaped, brown organs about the size of your fist. They are covered by the renal capsule, which is a tough capsule of fibrous connective tissue. Adhering to the surface of each kidney are two layers of fat to help cushion them.
What are the coverings of the kidney?
renal capsule, thin membranous sheath that covers the outer surface of each kidney. The capsule is composed of tough fibres, chiefly collagen and elastin (fibrous proteins), that help to support the kidney mass and protect the vital tissue from injury.
What is the basic anatomy of the kidney?
The kidneys are highly vascular (contain a lot of blood vessels) and are divided into three main regions: the renal cortex (outer region which contains about 1.25 million renal tubules), renal medulla (middle region which acts as a collecting chamber), and renal pelvis (inner region which receives urine through the …
What is studied in gross anatomy?
Gross anatomy involves the study of major body structures by dissection and observation and in its narrowest sense is concerned only with the human body.
What are the gross structures of the urinary system?
The organs of the urinary system include the kidneys, renal pelvis, ureters, bladder and urethra. The body takes nutrients from food and converts them to energy. After the body has taken the food components that it needs, waste products are left behind in the bowel and in the blood.
What structure protects the kidney quizlet?
1) renal capsule: is a tough fibrous outer skin of the kidney which protects it from injury and infection. 2)adipose capsule: is a fatty layer that protects the kidney from trauma.
What is the internal anatomy of the kidney?
Internally, the kidney has three regions—an outer cortex, a medulla in the middle, and the renal pelvis in the region called the hilum of the kidney. The hilum is the concave part of the bean-shape where blood vessels and nerves enter and exit the kidney; it is also the point of exit for the ureters.
Where are the kidneys located anatomy?
abdominal cavity
The kidneys are located at the rear wall of the abdominal cavity just above the waistline and are protected by the ribcage. They are considered retroperitoneal, which means that they lie behind the peritoneum.
What are the different approaches of gross anatomy?
Gross anatomy is further divided into three different fields: surface or superficial anatomy, regional anatomy, and systemic anatomy. The study of gross anatomy can be done on cadavers through dissection or with noninvasive methods through medical imaging.
