The capillaries are the site in the circulatory system where nutrients enter and wastes leave the tissues. The thin walls of the capillaries facilitate this diffusion.

The primary function of a lysosome is to break down waste materials like food particles or swallowed viruses or bacteria. It also digests worn out organelles. It is basically the stomach of an animal cell.
The main function of a cell membrane is to regulate the materials that enter or leave the cell. It ensures that nutrients can enter and wastes can be discarded from the cell.
The capillaries are the site of diffusion of wastes, oxygen, and nutrients. This allows these materials to enter and leave body tissues.

When nutrients are scarce, bacteria may enter a state of dormancy or slow their growth rate to conserve energy. They may also produce spores or biofilms to protect themselves from harsh conditions. In some cases, bacteria may also undergo genetic mutations to adapt to the nutrient-limited environment.
Nutrients from food and beverage is absorbed inside the walls of the small intestine. As we digest our food, all nutrients are taken in the small intestine and would most probably then enter our bloodstream from there on.
The job of the stomach is to kill bacteria that enter it. It contains Hydrochloric acid, a strong acid, but in a very dilute form. The acid does not break down food, but contains an enzyme called protease which breaks down proteins into polypeptide chains. No other digestion takes place in the stomach.
The cut allows a passage way for bacteria to enter your body. The bacteria enter. The infection forms because of the bacteria.
because you have to release the wastes from your body.
Raw materials and harmful wastes enter and exit the cells in your body by blood, the red blood carry oxygen from lungs to the body cells.
