It is the primary force that drives glomerular filtration. Free to share, print, make copies and changes.

Water tends to follow proteins based on an osmotic pressure gradient. • penis The male sexual organ for copulation and urination; also the tubular portion of the male genitalia (excluding the scrotum). • peri-tubular capillaries The capillaries through which components of filtrate are reabsorbed from the lumen of the nephron. • peristalsis The rhythmic, wave-like contraction of smooth muscle tissue that can propel substances through the many muscular tubes of the body. • peritubular capillaries Tiny blood vessels that travel alongside nephrons, allowing reabsorption and secretion between blood and the inner lumen of the nephron. • proximal tubule The first and primary sort of water and ion reabsorption in the kidney, where all glucose in the blood is reabsorbed.

Urine enters the bladder via the ureters and exits via the urethra. • urinary cast Tiny structures formed from bound abnormal cells and molecules within the nephrons that are excreted in urine. • urine A liquid excrement consisting of water, salts, and urea that is made in the kidneys then released through the urethra. • urine A liquid excrement that consists of water, salts, and urea, and is made in the kidneys then released through the urethra. • urine A liquid excrement consisting of water, salts, and urea that is made in the kidneys then released through the urethra. • urine A liquid excrement consisting of water, salts, and urea, which is made in the kidneys then released through the urethra. • urine A liquid excrement consisting of water, salts, and urea, which is made in the kidneys then released through the urethra. • vagina A fibromuscular tubular tract that is the female sex organ and has two main functions: sexual intercourse and childbirth.
