Do humans have a vascular system?
A vascular system distributes nutrients etc. and removes waste from the cells of the body. In humans this is controlled by the heart pumping blood around the body which is called the cardiovascular system. These systems are often referred to as the circulatory system. Yes, humans do have a vascular system. It consists of arteries and capillaries that carry oxygenated blood to the heart and other organs, veins that carry de-oxygenated blood from the organs to the lungs and then the heart for circulation. With age, veins may begin to lose their elasticity and strength. Veins, too, need a balanced diet to support their healthy functions. A good blend of nutrients, antioxidants and herbs help to keep veins strong and flexible supporting healthy circulation of blood throughout the body. Veins carry nutrients and oxygen that are required for the proper functions of all our organs. You can support vein health by taking supplements like Vein Matrix. The important herbs are horsechestnut, butcher's broom, Vitamin C.
How are the reproductive organs or a male and female the same and how are they different?
Organs repair themselves through a process of The gonads of the embryo begin to evolve into the sexual organs of the female at about the 10th or 11th week of pregnancy.

However, the testes evolve from the medulla of the gonad, whereas the ovaries develop from the cortex.
What is the order of cells systems and tissues?
The order of complexity begins with the cell as a functional unit. These cells work together to form tissues which work with other tissues to form organs. The organs work with other organs to form an organ system. The organ systems work all together to form a functioning organism.If you begin with a skeletal muscle cell and place many together that will make muscle tissues. Then add ligaments, tendons and bones (organs) to make the musculoskeletal system. This systems works with other systems in the body so that body will function naturally.
