Answer.
b). False.
Explanation.
Kidneys are responsible for urine formation that helps in removal of waste materials from the body. Urine formation involves three steps, filtration, reabsorption, and secretion.
During filtration, kidneys filter blood and collect water, glucose, amino acids, urea, and various slats and ions. Proteins and red blood cells are not filtered by the process of filtration. As glucose is important for body, it is reabsorbed by the body along with some other substances. Hence, red blood cells, proteins, and glucose are not secreted into the filtrate.
Thus, the given statement is 'false.'
Answer:
The pathway consists of several stages from formation to ejaculation.
Explanation:
The sperms are produced in seminiferous tubules in testes from where it is transferred and stored in the epididymis. Epididymis connects seminiferous tubule to vas deferens and during ejaculation peristalsis movement occur in smooth muscle of vas deferens which push sperms forward to ejaculatory duct.
From ejaculatory duct it enters in the urethra and finally it get ejaculated from penis due to the movement of muscles in the penis.
Capillaries. Capillaries absorb oxygen from inhaled air into the bloodstream and release carbon dioxide for exhalation. They are tiny vessels that branch out from arterioles to form networks around body cells.
