Biology Organs & Organ Systems: Human Body Overview

Organs & Organ Systems Agenda

Biology Organs & Organ SystemsAgenda for Today

• Organs . Organs SystemsName some organs!

Organs

• Organs are organized groups of tissue that perform a specific function
• What are some organ examples? Pharynx Brain Larynx Lymph nodes Heart Arteries Lungs Muscles Spleen Liver Bone marrow Gallbladder Stomach Kidneys Veins Skeleton Pancreas Intestines Urinary bladder

Organ Systems

• An organ system is a group of organs that function together to carry out specific duties in the body
• What are some organ systems? Brain Nasal passages Trachea Heart Liver Gall bladder Large intestine Blood vessels Small intestine Hair Cartilage Skin Bones Skeletal muscles Urinary bladder Tendons Joints Nails Thymus Pituitary glanc Lymph nodes Spleen - Pancreas - Epididymis - Ovaries Adrenal glands Testes Testes Uterus Lymphatic vessels Ovaries Stomach Spinal cord Lungs Peripheral nerves Kidneys Thyroid gland Mammary glands

Organ Systems That Coordinate Communication

Nervous System

Nervous System Network of cells specialized to detect, interpret, and respond to events occurring inside and outside of the body. Nervous system Endocrine system male female

Endocrine System

Secretes hormones Hormones affect functions such as development, reproduction, and how the body responds to stress.

Organ Systems That Acquire Energy

Digestive System

Digestive System Breaks down foods into molecules Molecules used as energy and as raw materials for use in the body Digestive system Circulatory system Respiratory system

Respiratory System

Exchanges oxygen and carbon dioxide between the lungs and the atmosphere. Breathe In: oxygen Breathe Out: carbon dioxide

Circulatory System

Transports important substances, including food molecules, oxygen, and carbon dioxide throughout the body.

Organ Systems That Support and Move the Body

Skeletal System

Skeletal System Bones, ligaments, and cartilage Protects soft organs and are points of attachment for muscles. Skeletal system Muscular system

Muscular System

The Muscular System Three types of muscle tissue provide movement for the body Skeletal - moves skeleton Smooth - enables movement within organs Cardiac - enables heart to beat

Organ Systems That Protect The Body

Urinary System

Urinary System Filters and excretes dissolved waste molecules. Keeps water, pH, and blood pressure levels in balance Kidneys, bladder

Integumentary System

Integumentary System Urinary system Integumentary system Immune and lymphatic systems

Immune System & Lymphatic System

Protect the body from infection, injury, and cancer. Skin, nails, hair Protects body, controls temperature, helps conserve water

Organ Systems That Produce The Next Generation

Reproductive System

Reproductive system male female Enables humans to reproduce Includes organs that make and transport sperm and eggs, as well as enable the female to give birth.
