The exchange of substances between the blood vessels and the surrounding tissues can only happen in the ___________.

natka813 [3]

Answer:

The exchange of substances between the blood vessels and the surrounding tissues can only happen in the <u>capillaries</u>.

Explanation:

Capillaries are the exchange vessels of our body. They form a network-like structure, called the capillary area. When blood, from the larger arterioles, spreads through the many capillaries in the capillary area, the blood pressure drops and the blood flows only at a slow speed. Through the thin, semi-permeable walls of the capillaries, the exchange of gas and substances between the blood and the surrounding tissue then takes place. Subsequently, blood continues to flow through the postcapillary venules, to which the capillary area has been reconnected. Blood pressure and blood flow increase and blood eventually reaches the heart through enlarged veins.

Temka [501]

Mitosis is a type of cell division for somatic cells and for the asexual reproduction of unicellular eukaryotic cells.

Meiosis is the type of cell division for the production of gametes in sexual reproduction . Meiosis is the process through which egg and sperm cells are formed. Mitosis is a necessary step for life.

A cell copies all of its components, including its chromosomes, and separates to generate two identical daughter cells during mitosis.

Meiosis is a form of cell division that occurs in sexually reproducing organisms and results in a reduction in the number of chromosomes in gametes (the sex cells, or egg and sperm).

Mitosis is the division of a single cell into two identical daughter cells (cell division).

Mitosis is a kind of cell division that occurs in somatic cells as well as in unicellular eukaryotic cells during asexual reproduction. Meiosis is a sort of cell division that occurs during sexual reproduction to produce gametes.
