How do the kidneys interact with the cardiovascular system?
Press to flip
The kidneys filter blood via the renal artery/vein and release renin to regulate blood pressure.
How do convoluted loops within the nephron contribute to its function?
Convoluted loops reabsorb water and nutrients and filter waste from protein digestion.
Explain how the urinary bladder signals the nervous system.
The urinary bladder signals the nervous system when it is full.
What is the nephron and its main components?
The nephron is the functional unit of the kidney, composed of the glomerulus, renal tubule, and collecting tubule.
What is the function of the urinary bladder in the urinary system?
The urinary bladder is an elastic, muscular sac that stores urine and is connected to the nervous system.
Describe the function of the ureter.
The ureter is a duct that leads from the kidney to the urinary bladder.
What is the significance of the nephron in urine production?
The nephron is responsible for filtering waste and absorbing nutrients, crucial for urine production.
What role do the kidneys play in red blood cell production?
The kidneys produce hormones that stimulate the production of red blood cells.
What are the five key functions of the kidneys?
Make urine from protein breakdown waste, filter blood of salt, nutrients, water, and waste, maintain water homeostasis, maintain blood pressure, activate vitamin D.
Explain the role of the glomerulus in the nephron.
The glomerulus filters out blood cells using blood pressure.
How do the kidneys activate vitamin D?
The kidneys activate vitamin D in conjunction with the skin.
How do kidneys help maintain blood pressure?
Kidneys maintain blood pressure by filtering blood and releasing renin.
Describe the three regions of the kidneys and their main functions.
Cortex: outer layer with blood vessels and nephrons, produces hormone for red blood cells. Medulla: inner layer with nephrons, urine concentration, salt-water balance. Renal Pelvis: central collecting region, drains waste fluid into ureters.
Discuss the role of the urethra in the urinary system.
The urethra is a tube that extends from the urinary bladder to the outside of the body.
Why is understanding the functional anatomy of kidneys important for the TEAS exam?
Understanding kidney anatomy and functions is crucial for questions related to the genital urinary system on the TEAS.
