• Brain


  The control center of our body, like the boss of a company. It tells all the other parts of our body what to do.
• Cerebrum


  • The biggest part of the brain. It helps us think, learn, remember, and make decisions.
• Lobes of the Cerebrum

  • Frontal Lobe
  • Parietal Lobe
  • Occipital Lobe
  • Temporal Lobe
• Frontal Lobe


  Helps with thinking, planning, problem-solving, and controlling our behavior and emotions.
• Parietal Lobe


  Processes information from our senses, like touch, taste, and temperature.
• Occipital Lobe


  Helps us see and understand what we are looking at.
• Temporal Lobe


  Helps us hear, understand language, and remember things.
• Cerebellum


  Smaller and sits under the cerebrum at the back of the brain. It helps with balance, coordination, and movement.
• Brainstem


  Connects the brain to the spinal cord. It controls basic functions that keep us alive, like breathing, heart rate, and digestion. It's also in charge of our reflexes, like blinking and swallowing.
• Limbic System


  Deep inside the brain and helps control our emotions and memories.
• Amygdala


  Helps us feel and react to emotions like fear, anger, and happiness.
• Hippocampus


  Helps us form and store memories. It helps us remember things like our name, address, and what we did yesterday.
• Thalamus


  Like a relay station. It sends messages from our senses (except smell) to the right parts of the brain.
• Hypothalamus


  A small part of the brain that controls important things like body temperature, hunger, thirst, and sleep. It helps keep our body in balance.
• Neurons


  The brain is made up of billions of tiny cells that send and receive messages through electrical signals.
• Synapses


  Neurons connect to each other at places called synapses, where they pass messages using chemicals called neurotransmitters.
• Lobes of the Brain

  • Frontal Lobe
  • Parietal Lobe
  • Occipital Lobe
  • Temporal Lobe
• Skull


  The hard bone that protects the brain from injury.
• Cerebrospinal Fluid


  Fluid that surrounds the brain and acts like a cushion to protect it from bumps and knocks.
• Healthy Habits


  • Eating healthy food
  • Getting enough sleep
  • Wearing a helmet when biking
  • Avoiding harmful substances
• Practice


  The more we practice something, the stronger the connections between neurons become.
• Sleep


  Getting enough sleep helps our brain process and remember what we learned during the day.
• Healthy Food


  Eating foods like fish, nuts, and vegetables helps our brain stay strong and healthy.
• Amygdala


  This small part of the brain helps us feel emotions like happiness, fear, and anger.
• Managing Emotions


  Talking about our feelings, taking deep breaths, and doing things we enjoy can help us manage our emotions.
• Even though the brain is only about 2% of our body weight, it uses about 20% of our energy.
• The brain grows a lot in the first few years of life and keeps developing until we are about 25 years old.
• Neuroplasticity


  The brain's ability to change and adapt when we learn new things or experience new situations.
• Heart


  A strong muscle in your chest that pumps blood all around your body. It is about the size of your fist.
• Parts of the Heart

  • Atriums
  • Ventricles
  • Valves
• Atriums


  The two upper chambers of the heart that receive blood coming into the heart.
• Ventricles


  The two lower chambers of the heart that pump blood out of the heart.
• Valves


  Act like doors that open and close to make sure blood flows in the right direction and doesn't go backward.
• Blood Flow


  1. Right Side: Receives blood from the body and pumps it to the lungs to pick up oxygen.

  2. Left Side: Receives the oxygen-rich blood from the lungs and pumps it out to the rest of the body.
• Heartbeats


  The heart beats to push blood through the body, about 60-100 times every minute.
• Blood Vessels


  • Arteries
  • Veins
  • Capillaries
• Arteries


  Blood vessels that carry oxygen-rich blood away from the heart to the rest of the body.
• Veins


  Blood vessels that carry blood back to the heart after it has delivered oxygen and nutrients to the body.
• Capillaries


  Tiny blood vessels where the exchange of oxygen, nutrients, and waste happens between the blood and body tissues.
• Ways to Keep Your Heart Healthy

  • Exercise
  • Healthy Eating
  • No Smoking
  • Regular Check-ups
