The nursing instructor informs the students that which anatomical structure controls the elimination of urine from the body?

Tomtit [17]

The Urinary bladder controls the elimination of urine from the body.

The lower abdomen contains this triangle-shaped, hollow organ. Ligaments that are connected to the pelvic bones and other organs hold it in place.
When storing pee, the bladder's walls relax and expand; when emptying urine through the urethra, they contract and flatten.
The typical healthy adult bladder has a two to five-hour storage capacity of up to two cups of urine.

Three parts of bladder allow urine to be discharged:

A pair of sphincter muscles. By tightly shutting around the bladder opening like a rubber band, these circular muscles assist prevent urine leakage.
In the bladder's nerves. When it's time to urinate or empty the bladder, the nerves let the person know.
Urethra. Urine can travel through this tube and leave the body. Urine leaks from the bladder as a result of the brain's tightening signal to the bladder muscles.

Animal and Plant Cell Organelles Use the drop-down menus to determine where these organelles can be found. Ribosome Endoplasmic

rjkz [21]

Answer:

Animal Cell:

Ribosome, Endoplasmic reticulum, Golgi apparatus, small Vacuoles, Lysosomes, Mitochondria, Cell membrane, Cytoplasm.

Plant Cell:

Ribosome, Endoplasmic reticulum, Golgi apparatus, Cell wall, Big Vacuole, Lysosomes, Mitochondria, Cell membrane, Cytoplasm, Chloroplasts.

Explanation:

<u> Animal Cells Vegetable Cells</u>

Cell wall NO YES

Vacuoles YES, Small and more than ones YES, Only one and big

Chloroplast NO YES

Plasmatic membrane YES YES

Mitochondria YES YES

Lysosomes YES YES

Endoplasmic reticulum YES YES

Golgi apparatus YES YES

Cytoplasm YES YES

Ribosome YES YES

Both the animal and plant cells are eukaryotic. They carry their genetic material in the nucleus and mitochondria. Organelles are located in the cytosol, and both of them are surrounded by a protector cell membrane.

However, they have some differences:

<u>Cell wall</u>: A rigid structure that provides support and protection.

Animal cells do not have a cell wall. They are only surrounded by the cell membrane, which is flexible, so they can adopt different shapes.
Plant cells have a wall, so their shape is usually prismatic and regular. The cell wall is composed mainly of cellulose.

<u>Chloroplast:</u> these are organelles that accumulate chlorophyll.

Animal cells do not have chloroplasts because they do not photosynthesize.
Plant cells have chloroplasts, and they are in charge of the photosynthesis process that allows plants to release oxygen. These organelles use solar light as the source of energy.

<u>Vacuoles</u>:

Animal cells have many and small vacuoles whose function is to store water, ions, and waste intracellular substances.

Plant cells have a unique big-sized vacuole that might occupy almost 90% of the cell. Their principal function is to store water and keep the turgidity. When the vacuole gets empty, the plant loses rigidity.

Other differences are:

The animal cell has centrioles, while the vegetable cell does not.

Plasmodium, chromoplasts, and glyoxysomes are present in the vegetable cell but not in the animal cell.
