Functions of the kidney include: 1. removing waste products from the blood. 2. maintaining fluid and electrolyte balance. 3. secreting substances that affect blood pressure.

Explanation:

1. One of the major function of the kidney is to excrete metabolic waste. When the blood is perfused through the Bowman's capsule, an ultrafiltrate of the blood is produced in the glomerulus, the filtrate in Bowman's capsule contains salt, glucose, amino acids, nitrogenous waste, etc while the cells and proteins are retained in the blood. The waste are excreted as urine or uric acid.

2. One of the function of the renal tubule is to maintain fluid and electrolytes balance. When the glomerulus filtrate is formed, it contains almost all the crystalloids of plasma which includes water, Na+, Cl-, glucose, amino acid and K+. The renal tubule reabsorb water and solute to the blood to maintain water and electrolytes balance.

3. The kidney secrete a hormone Renin, which control other hormones angiotensin and aldosterone that helps to control blood pressure.

interphase

the period of cell growth when the cell synthesizes new molecules and organelles. the cell is not dividing and it constitutes the majority of the time spent in the cell cycle

prophase

changes occur in the nucleus and cytoplasm. the chromatin condenses to form structures (sister chromatids) visible with a light microscope and the mitotic spindle begins to form, but the nucleus is still in tact

prometaphase

the nuclear envelope fragments and the spindle microtubules attach to the kinetochores of the sister chromatids

metaphase

all the cell's duplicated chromosomes are lined up at an imaginary plane equidistant between the poles of the mitotic spindle

anaphase

begins when sister chromatids separate from each other and ending when a complete set of daughter chromosomes arrives at each of the two poles of the cell

telophase

the daughter nuclei form at the two poles of a cell

cytokinesis

the division of a cytoplasm to form two separate daughter cells. usually occurs during telophase during mitosis. this and mitosis make up to mitotic (m) phase of the cell cycle
