Answer:
increasing pressure inside the lymph capillary
Explanation:
Lymph is a fluid like the blood which carry the White blood cells which can fight against the infection. The lymph flows in separate vessels called lymphatic vessels.
The lymphatic vessel is very thin-walled smooth muscle containing tube-like structure which allows the transport of lymph.
The lymph vessel like blood vessel contains the valves called mini valves which prevent the backward flow of the lymph.
When the pressure in the tiny lymph capillaries which supplies lymph to the organs increases, the mini valves closes to prevent backflow of lymph and is the mechanism of lymph flow.
Thus, the selected option is the correct answer.
Answer:
The color of skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis.
Answer:
Hiya there!
Explanation:
ATP then binds to myosin, moving the myosin to its high-energy state, releasing the myosin head from the actin active site. ATP can then attach to myosin, which allows the cross-bridge cycle to start again; further muscle contraction can occur.
acetylcholine
: Skeletal muscle contraction and changes with exercise. (A) Neurotransmitter (acetylcholine, ACh) released from nerve endings binds to receptors (AChRs) on the muscle surface.
The muscle contraction cycle is triggered by calcium ions binding to the protein complex troponin, exposing the active-binding sites on the actin. As soon as the actin-binding sites are uncovered, the high-energy myosin head bridges the gap, forming a cross-bridge.
