What are the tubes that flow through the in the body?
Blood vessels such as arteries, veins, and capillaries are the tubes that carry blood throughout the body. Other tubes include the digestive tract (esophagus, stomach, intestines), airways (trachea, bronchi), and the urinary system (ureters, bladder, urethra).
What tubes carry water and FOOD?
The xylem tubes in plants carry water from the roots to the leaves, while the phloem tubes transport food (sugars) produced in the leaves to other parts of the plant for storage or growth.
What are the tubes called in plants the carry water into the plant?
This is the vascular tissue xylem.
What is a network of tubes that hold the ribosomes?
The endoplasmic reticulum (ER) is the network of tubes inside a cell that holds the ribosomes. There are two types of ER: rough ER, which has ribosomes attached to its surface, and smooth ER, which does not have ribosomes. The ribosomes on rough ER are involved in protein synthesis.
What makes the blood flow through the blood tubes?
Blood flow through blood vessels is facilitated by the pumping action of the heart. The heart's rhythmic contractions create pressure that propels blood through arteries, then smaller arterioles, and eventually into capillaries. Once oxygen and nutrients are exchanged in the tissues, blood returns to the heart through venules and veins, aided by one-way valves and muscle contractions.
