The circulatory system is mainly made up of the heart and the blood vessels. It is closely related to the respiratory system which is primarily made up of the lungs. The digestive system is primarily made up of the gastrointestinal tract. This simply means your mouth, esophagus, stomach, small and large intestines, and rectum up until your anus. All the cells in the human body are kept alive by these systems working together in harmony.
The heart pumps blood throughout the whole body via the blood vessels. Blood, particularly red blood cells (RBC), carry oxygen and nutrients inside of them and release them to the other cells in the body. Oxygen comes from the lungs in the respiratory system every time we breathe in air. Nutrients come from the digestive system after food has been broken down to small components that can be utilized by the cells in the body.
The answer is 3’-tactttaggatc-5’. This is complementary to 5'-augaaauccuag-3' of the mRNA. It is important to note that RNA has no thiamine but instead has uracil (Thymine is a methylated form of Uracil.). The other principles on bae pairing apply where C pairs with G, and U with A. Thiamine is used in DNA because it gives it more stability than uracil does.
During body temperature regulation, temperature receptors in the skin communicate information to the brain (the control center) which signals the effectors: blood vessels and sweat glands in the skin.
