There are four main types of tissues in the human body: epithelial, connective, muscle, and nervous tissue. Epithelial tissues cover and line body surfaces, and can be simple or stratified. Connective tissues are found throughout the body and include bone, cartilage, blood, adipose, and fibrous tissues that connect and support other tissues. Muscle tissues include skeletal, smooth and cardiac muscle. Nervous tissues are made up of neurons and neuroglia and are responsible for processing and transmitting information.
TNM staging is a system used to describe the extent of cancer in the ampulla of Vater, bile ducts, and pancreas based on the size of the original tumor (T), whether the cancer has spread to nearby lymph nodes (N), and whether the cancer has metastasized to distant organs (M).
The document discusses the benefits of exercise for mental health. It notes that regular physical activity can help reduce anxiety and depression and improve mood and cognitive function. Exercise has also been shown to enhance self-esteem and serve as a healthy distraction from daily stressors.

The document provides an overview of the endocrine system, including:
- The endocrine system secretes hormones directly into the bloodstream to regulate functions, unlike the nervous system.
- Hormones include steroidal hormones like estrogen and cortisol, and nonsteroidal hormones made of proteins.
- Negative and positive feedback loops control hormone levels.
- Key endocrine glands are the hypothalamus, pituitary gland, thyroid gland, parathyroid glands, adrenal glands, pancreas, and gonads.
- Stress causes the release of hormones that increase heart rate, respiration, blood glucose/fatty acids, and can suppress the immune system if prolonged.
- Common endocrine
