Answer:
The factor favoring filtrate formation at the glomerulus is the <u>glomerular hydrostatic pressure.</u>
Explanation:
glomerular hydrostatic pressure is the pressure of the blood in the glomerular capillaries.
The pressure generated by the fluid against a surface is called the Hydrostatic pressure . The blood in glomerulus generates the glomerular hydrostatic pressure , that forces the fluid out of glomerulus into the glomerular capsule .
Fluid in glomerular capsule generates pressure that pushes the fluid out of glomerular capsule back into the glomerulus , opposing glomerular hydrostatic pressure . this is called the capsular hydrostatic pressure .
The fluid exerts pressure in the opposite direction , and hence , the net movement of the fluid will be in the direction of lower pressure .
Answer:
The correct answer is D.
Explanation:
Sperm is produced in the seminiferous tubules of the testes, then it travels through the straight tubules and the rete testis and arrives at the <u>epididymis to mature and to be stored.</u>
When ejaculation occurs, sperm leaves the epididymis through the vas deferens and arrives to the ejaculatory duct. Then ejaculatory duct passes through the prostate to merge witch the urethra and finally sperm leaves the body.
