State the major processes of the urinary system and describe the activity of each process.
Dennis_Churaev [7]

Answer:

The urinary system removes excess substances and waste products from the metabolism from the body through the urine, contributing to the maintenance of homeostasis, the chemical composition of the internal environment. Urine is produced in the kidneys, passes through the ureters to the bladder, where it is stored and is released into the exterior through the urethra.

The kidneys perform the main work of the urinary system comparing with the other parts of the system, acting primarily as passageways and storage areas. With the filtration of blood and the formation of urine, the kidneys contribute to homeostasis of body fluids in a number of ways, such as: Regulation of the ionic composition of blood; Maintenance of blood osmolarity; Regulation of blood volume; Blood pressure regulation; PH regulation of blood; Hormone release; Regulation of blood glucose level; Waste excretion and toxic substances.

Ureters - They are two tubes that carry urine from the kidneys to the bladder. The ureters are capable of performing rhythmic contractions called peristalsis. Urine moves along the ureters in response to gravity and peristalsis.

Bladder - The urinary bladder acts as a temporary reservoir for urine storage. It is a hollow, elastic muscular organ that in men is directly anterior to the rectum and in women, is located in front of the vagina and below the uterus.

Urethra - is a tube that conducts urine from the bladder to the outside, being lined with mucosa that contains a large amount of mucus-secreting glands. The urethra opens outwards through the outer ostium of the urethra.

What is an anterior pituitary hormone?
kicyunya [14]

Answer:

The pituitary gland refers to a small gland, which is situated in the sella turcica. It is considered the master gland of the body. The pituitary gland comprises two prime parts, the posterior pituitary gland and the anterior pituitary gland. The anterior pituitary gland produces six hormones and discharged them into the bloodstream.  

The following are the hormones produced by anterior pituitary gland:  

1. The growth hormone that monitors metabolism, growth and body composition.  

2. Adrenocorticotropic hormone that instigates the adrenal glands to produce steroid hormones, mainly cortisol.  

3. Follicle-stimulating hormone and luteinizing hormone, also called gonadotropins, which functions on the testes or ovaries to instigate the production of sex hormone, and maturity of sperm and egg.  

4. The thyroid-stimulating hormone that instigates the thyroid gland to discharge thyroid hormones.  

5. Prolactin that instigates the production of milk.

For the numbered steps below, select the option that places them in the correct order. 1) The ribosome binds to the mRNA and use
MrRissso [65]

Answer:

first 4, then 2, then 1, and lastly 3

Explanation:

First, RNA polymerase binds to the promoter region of a gene on the DNA and initiates transcription. Transcription is the process by which we get mRNA (coding RNA) which is used as a template for protein synthesis. Then, in transcription, the resulting mRNA undergoes modification and maturation. This  involves removal of introns, addition of 3'-poly-A tail and 5'-cap. Introns are sequences that do not code for protein and are hence removed. The structure that removes introns is the spliceosome. Thirdly, mature mRNA travels to the cytoplasm. Ribosome (composed of rRNA) binds to mRNA and tRNA to start the process of protein synthesis. The process of formation of protein is called translation. Lastly, the primary structure of protein may undergo folding to form a tertiary structure.
