How does prostaglandin cause vasodilation?
Most prostaglandins act locally; for instance, they are powerful locally acting vasodilators. Vasodilation occurs when the muscles in the walls of blood vessels relax so that the vessels dilate. This creates less resistance to blood flow and allows blood flow to increase and blood pressure to decrease.
What do you mean by prostaglandins?
The prostaglandins are a group of lipids made at sites of tissue damage or infection that are involved in dealing with injury and illness. They control processes such as inflammation, blood flow, the formation of blood clots and the induction of labour.
What organs repair themselves through a process of?
Every day your body cells are dividing using a process called mitosis. This allows you to grow and replace damaged or worn out cells.
When the chromosomes line up in mitosis This is known as which phase *?
Metaphase. Chromosomes line up at the metaphase plate, under tension from the mitotic spindle. The two sister chromatids of each chromosome are captured by microtubules from opposite spindle poles. In metaphase, the spindle has captured all the chromosomes and lined them up at the middle of the cell, ready to divide.
Which cellular organelle contains enzymes that are considered digestive?
A lysosome is a membrane-bound cell organelle that contains digestive enzymes. Lysosomes are involved with various cell processes. They break down excess or worn-out cell parts.
When the chromosomes line up in mitosis This is known as which phase telophase anaphase metaphase prophase?
Mitosis has four sequential stages: prophase, metaphase, anaphase, and telophase. In prophase, each chromosome becomes condensed and more visible, and there is the breakdown of the nuclear membrane and appearance of spindle fibers. In the next phase, metaphase, the chromosomes line up along the metaphase plate.
