The answer is skin

The first line of defence is your innate immune system. Level one of this system consists of physical barriers like your skin and the mucosal lining in your respiratory tract. The tears, sweat, saliva and mucous produced by the skin and mucosal lining are part of that physical barrier, too.

Common behaviors that are a result of Alzheimer's disease are
Liula [17]

Answer:

angry outbursts and physical aggression, hand wringing pacing and rocking, accusing loved ones of wrong doing and hallucinating, repeating stories and leaving the house unassisted, sleep problems and sundowing

Explanation:

1, Verbal or physical aggression, which can be quite alarming, is common in patients with Alzheimer’s.

2, Dementia makes it very difficult to process stimuli and new information, causing many people with Alzheimer’s disease to become anxious. 

3, Caregivers may feel at a loss when an Alzheimer’s patient exhibits behavior that is clearly not grounded in reality: either hallucinations—perceiving something that isn’t really there—or delusions, which are false beliefs that can lead to paranoia.

4, The memory problems caused by Alzheimer’s disease can lead to a range of distressing behaviors, including repetition of words or activities, disorientation even in familiar places, and, in severe cases, confusion about the passage of time.

5, It’s not well understood why sleep disturbances occur in many Alzheimer’s patients, but it’s common for them to experience nighttime restlessness and changes to their sleep schedule.

Greater decreases in overall brain volume in later adulthood is associated with ________________ in cognitive abilities and cogn
TEA [102]

Greater decreases in overall brain volume in later adulthood is associated with an unclear exact relationship in cognitive abilities and cognitive functioning.

<h3>How brain changes in late adulthood?</h3>

The brain's size reaches roughly 90% of its adult volume by the time a child is six years old. The brain begins to contract in our 30s and 40s, and by the time we reach our 60s, the brain is contracting even more rapidly. The brain begins to change in appearance, just like wrinkles and gray hair do later in life.

The brain actually shrinks and its overall mass decreases as adults. There are decreases in some neurotransmitters as well, including dopamine and acetylcholine. Loss of memory for recent events, familiar names, and familiar duties is the first sign of Alzheimer's disease. In old age, general knowledge memory does not deteriorate. There has been a deterioration in episodic and event memory.
